PASTING-MACHINE.

Specification of Letters Patent.

Patented Feb. 18, 1908.

Application filed May 28. 1907.,` Serial No, 376.119.

To all whom it may concern:

lBe it known that I, NICHOLAS Sor-momen, a citizen of the United States, residing in the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a certain new and useful Improvement in Fasting-Machines, of which the following is a specification.

The invention relates to machines for applying an adhesive to sheets of paper and analogous material and attaching such sheets to various articles, and more particularly to machines for aflixing flies to the interior of paperboxes.

The object of the invention is to provide a machine by which the operations of applying the paste and attaching the flies to the inner margins of the boxes may be economically and accurately performed and which shall be simple in construction and easily operated.

The invention consists in certain novel features and details of construction by which the above objects are attained, to be hereinafter described.

The accompanying drawings form a par of this specification and show a preferred form of the invention.

Figure l is a front view of the machine. Fig. 2 is a side view, and Fig. 3 is a plan view of certain portions, partly in horizontal section. Figs. 4 and 5 are vertical sections on a larger scale, showing the paste-trough and adjacent parts in several positions as-v sumed in the pasting and attaching operations. Fig. 6 is a longitudinal vertical section showing a portion of the pastetrough on a still larger scale, and Fig. 7 is a corresponding transverse section.

Similar fletters of reference indicate the same parts in all the figures.

A is the frame of the machine, comprising four upright posts joined by horizontal braces and inclosing a iixed table B at a height convenient for the operator. Cn the table B is a bed C arranged to slide in guides B1 extending from front to rear and carries the pack of superposed flies M at the front. The pack is loosely inclosed between a fixed ledge B2 at one end, an adjustable gage C1 at the opposite end, and a similar gage C2 at the rear; the front of the pack lies about flush with the front edge of the bed and is confined at this edge by the upturned ends or ngers C3 of ilat springs C4 attached to the under face ofthe bed.

Lying loosely on the upper surface of the pack is a weight comprising a bar D supported on curled strips of metal D1 extended rearwardly in the form of arms D2 having holes d in which are engaged pins c on the upper edge of the rear gage C2, as shown, so r angular cross-section, arranged to slidever tically in ways A2 on the front posts of the frame. It is open at the top to receive paste and the bottom is formed of a strip of sheet metal E1 semicircular in cross-section, with a line of small perforations e along the center line of its lower convex face through which paste from the interior of the trough is delivered to the upper face of the topmost fly of the pack` Cn the oblique rear face of the trough is a strip or follower -E2 projecting downwardly beyond the bottom of the trough and closely adjacent thereto. It is arranged to slide vertically by rods E.3 attached' thereto and passing througheyes or loops ElL on the trough. The upper ends of the rods E3 are screw-threaded and loosely engaged with levers E5 extending across the open top of the trough and fulcrumed at e1 on the top edge of the front board thereof. Nuts Ei on the rods above and below the levers adjustably connect these parts and the weight of the follower is sufficient to hold it in the lowered position until it rests upon the pack when the trough is lowered. Suspended .from the levers E5 is a round bar E7 lying in the concave trough-bottom and serving to open or close the erforations c according as the follower an levers are raised or lowered relatively to the trough. Forward of the trough and sliding in ways A3 on the same posts and parallel with the ways A3, is a presser F in the form of a flat board or plate having a plane lower edge and servin to press the box downward against the paste upper 'Hy of the pack.

In the machine as illustrated the several motions are produced by foot-levers G and H through cords extending therefrom over guide sheaves and pulleys to the bed, trough, and presser which are returned b the action of weights similarly connecte l. It will be understood that springs may be employed instead of the weights, and the motions may be induced by cams or other mechanism acting on the foot-levers or their equivalents.

The paste-trough is held in the elevated position by the gravity of weights I I attached to cords I1 I1 running over pulleys I2 I2 on the top of the frame and fastened to the trough at its ends, and is depressed by the foot-lever II through cords I3 I3 ruiming therefrom over guide-sheaves I4 I4 and I5 I5 and secured to the trough at I6 I".

Weights J J on the cords Jl J1 from the presser F, running over pulleys J2 J2 similarly elevate this portion of the mechanism which is depressed by the foot-lever G through cords J3 J3 running on guide-sheaves J4 J4 and J5 J5 and attached to the presser at J 6 J 3.

Attached to the under face of the bed C near the front is a cord K1 running over a pulley K2 on the frame atV the rear and carrying a weight K serving to draw the bed with its pack of flies and attachments toward the rear g the forward movement is induced by the descent of the foot-lever G through the medium of a cord K3 running over a pulley K4 at the front and fastened to the bed C near the rear, The cords K1 K3 lie in a narrow space t provided in the table B, and the latter is also grooved as at b1 b4 to permit the depression of the spring-fingers C3 C3.

The operation of the machine is as follows :mAssuming the trough to be supplied ywith paste, and, with the presser F, to be in the elevated position, and the bed C retracted and carrying a pack of flies so placed that the forward edge of the pack lies close to the fingers C3, it will be seen by referring to Fig. 4 that the margin of the top-most fly M is directly below the line of perforations in the bottom of the trough; by depressing the foot-lever H the trough is lowered to apply the paste, but before such contact the follower E2Istrikes the fly and through its rods E3 and the levers holds the bar E7 against further descent and thus releases the paste which is then delivered by the continued downward movement of the trough, as indicated in the dotted lines in the figure. The foot-lever is now released and the trough begins to rise while the follower by gravity holds down the pasted fly until adherence of the latter to the trough is broken and the trough rises sufficiently to close the perforations by the bar E7, when it also is lifted with the trough to the fully elevated position clear of the pack and the weight D thereon. The foot-lever G is then depressed, forcing the bed C forward, the operator at this time applies the open face of a box N to the bed with the inner surface of its side-wall above the pasted margin of the fly and resting lightly upon the ends of the spring-fingers C3. The further descent of the foot-lever G brings the presser F down on the exterior of the box and forces it down in opposition to the force of the spring-fingers into close contact with the pasted margin of the fly, as shown in Fig. 5, spreading the paste by pressure and insuring complete union. The release of the footlever G allows the presser to rise and the bed C to recede and the spring-fingers lift the box with its attached fly adhering thereto, thus separating the ily from the pack, and it is finally drawn from beneath the weight D by the withdrawal of the box, the spring-lingers preventing the succeeding fly or flies from following it.

The paste-trough is of sufficient length to operate on the longest flies, but as the latter vary in length to conform to the length of boxes, it is necessary to reduce the effective length of the pasting line accordingly so that the machine may be adapted to serve on all sizes. This Iis accomplished by a thin slide or gate L curved to match to the inner concave face of the trough-bottom, introduced at one end thereof and covering the holes e; by inserting it the proper distance the desired length of pasting line is obtained, and, by reason of the thin metal used in its construction, it does not interfere with the closing action of the bar E7 upon the remaining uncovered perforations.

On the front edge of the bed C is a series of notches c4 each adapted to receive one end-wall of a box to be treated, the other end-wall lying closely adjacent to the side of the bed, thus permitting boxes of different lengths to be operated upon with flies of corresponding lengths.

The connections between the bar E7 and levers E5 are adjustable, and with the similarly connected rods E3 from the follower permit these parts to be conditioned to control the flow of paste and the action of the follower on the fly, and the adjustable gages y Cl C2 permit packs of various lengths and widths to be properly presented.

It will be observed that the machine is of few parts, simplyv constructed and easily operated.

The cords confer an elasticity or yielding quality to the pressure of the paste-supplying and pressing operations which is of advantage in a machine of this character, and permit the pasting to be properly eected irrespective of the thickness of the fly-pack, thus obviating the necessity of compensating mechanism for this purpose, but the several movements may be produced by other and more positive means, and the mechanism adapted for other purposes than fly pasting.
